Hi to all
I am repairing a Fiesta 1117cc 1993 with CFI for a MOT retest one of the failure items is emisions like
fails CO test 0.79 passes HC at 178 Lambda pass at 1.03
so to sum up just fails on the CO should be up to 0.30 max I guess the cat has failed do you agree as this car belongs to a student and I am trying to keep costs down. The engine has had a full service in the last 6 x months
thanks in advance mike
